Visual environment of rearing sites affects larval response to perceived risk

The paper investigates how larval rearing environments with different light levels affect tadpole responses to visual risk cues, finding that turbid conditions reduce response strength in some species.

Diet influences resource allocation in chemical defence but not melanin synthesis in an aposematic moth

The paper tests how larval diet affects chemical defence and melanin synthesis in moths, finding resource trade-offs in defences but not in melanin.

Genetic factors influence behavioural repeatability in juvenile poison frogs

This study investigates whether activity levels in juvenile poison frogs are repeatable and finds family-level repeatability, suggesting genetic factors influence behavior.

Not just the sum of its parts: geographic variation and non-additive effects of pyrazines in the chemical defence of an aposematic moth

The paper investigates geographic variation and non-additive effects of pyrazines in the chemical defence of the wood tiger moth, finding that SBMP and IBMP have complex interactions and efficacy depending on concentration and predator context.

Contrasting parental roles shape sex differences in poison frog space use but not navigational performance

This study examines sex differences in poison frog spatial behavior and finds that parental roles influence space use but not navigational performance, challenging the adaptive specialization hypothesis.

Pool choice in a vertical landscape: tadpole rearing site flexibility in phytotelm-breeding frogs

This study examines the flexibility of tadpole rearing site selection in three Neotropical frog species, finding differences in their use of phytotelm pools based on chemical, physical, and vertical factors.

Size-dependent tradeoffs in aggressive behavior towards kin

The paper investigates how size and relatedness influence aggressive behavior in cannibalistic Dendrobates tinctorius tadpoles, finding that size and relatedness interact to predict aggression.

Visible implant elastomer (VIE) success in early larval stages of a tropical amphibian species

The paper successfully applies VIE tags to early larval stages of Dendrobates tinctorius tadpoles and reports high tag retention and no adverse effects on growth or survival.

Geographic mosaic of selection by avian predators on hindwing warning colour in a polymorphic aposematic moth

The paper shows that avian predator selection on warning coloration in moths varies geographically, with stronger positive frequency-dependent selection in monomorphic populations and weaker selection in polymorphic ones.

Much more than a clasp: Evolutionary pattern of amplexus diversity in anurans

The paper reconstructs the evolutionary history of amplexus in anurans, finding 35 transitions and high phylogenetic conservation, with no link to sexual size dimorphism.

From Habitat Use to Social Behavior: Natural History of a Voiceless Poison Frog, Dendrobates tinctorius

This study documents the natural history of Dendrobates tinctorius, focusing on habitat use, social behavior, and life cycle stages to inform future research on ecology and conservation.
